Answer 1

Answer:

40°

Step-by-step explanation:

Angle BOC=2XANGLE BAC =2×50=100°

In ∆OBC, OB=OC

SO, ANGLE OBC= ANGLE OCB

SO, X=(180°-100°)/2=40°

Answer 2

Step-by-step explanation:

Here,

IN TRI BAC,

BAC = 50

BOC = 2BAC

= 2( 50 )

= 100

NOW ,

IN TRI BOC ,

OB = OC

: . OCB = OBC

SO,

: . OCB + OBC + BOC = 180 ( ASP )

: . OBC + OBC + 100 = 180

: . 2OBC = 180 -- 100

: . OBC = 80 ÷ 2

: . OBC = 40

: . OBC = X = 40
